Nitrous Oxide (Laughing Gas)

A colorless, odorless gas ($N_2O$) inhaled through a small nasal mask. It is a mild sedative that induces a state of relaxation and euphoria, commonly known as "Laughing Gas."

Why It Matters

It is the safest form of sedation, ideal for children or patients with mild anxiety. Unlike oral sedation pills, the effects wear off within minutes of breathing pure oxygen, allowing patients to drive themselves home.

Clinical Details

• Mechanism: Depresses the central nervous system to raise the pain threshold and reduce the gag reflex.
